Modify linenoise.c so that it can build with -std=c89. Baseline linenoise.c relied on snprintf(), strdup(), and strcasecmp() which are technically not in C89. Since linenoise.c's only purpose (at present) is to implement the SQLite shell, make use of the SQLite compatibility functions. Following this change, "fossil clean -f && CFLAGS='-std=c89 -Wall' ./configure && make" builds without warnings or errors on gcc 4.4.7 20120313 (Red Hat 4.4.7-3) on CentOS release 6.4 (Final). Unrelated note: discovered during testing that "CFLAGS=-Werror ./configure" fails to add -lm to link step due to conflicting types for built-in function "sin" being regarded as an error.
